Ouch! Machines have only one purpose, and that is to deliver the equivalent pain of a number of bites and stings of the various terrors of the insect world.

There is always a certain type of person who wonders what it might feel like to be bitten by a giant centipede, or stung by a poisonous jelly
fish. Tales of hands being put into boiling water to quell the resulting anguish are common, but just how bad is it? No need to wonder any more, with the Ouch! Machine at your service.

The machine itself is simple. You just rotate the large dial until it points to the beastly selection, then set the secondary timer control to either short and sharp, or numbingly long. You then enter some personal details that conclude with waiving the machine owner of all responsibility. Finally you place the limb of your choice into the machine's action chamber, and feed it some money.

Following a short countdown your bite/sting of choice is delivered [by a combination of mechanical jaws/needle(s)]. As a small reward, your details are used to generate a lurid certificate, verifying that you have received a simulated bite by the hideous insect/creature you had selected.

These machines would probably find plenty of willing customers in sports bars and other such venues, where the fool-hardy are always keen to subject themselves to torturous enterprises in order to prove something or other.

Apart from qualifying you for the Bene Gesserit, this would
be useful for patients with chronic pain. Those
unfortunates are asked to rate their suffering on a 1 to 10
scale, with 10 being "the worst pain you can imagine." It's
invaluable, but impossible to do really correctly. How bad
is the worst imaginable pain? Some patients rate their
pain as "10," but I've often suspected that this only
reflects their limited imagination. I'll bet Torquemada, for
example, had a few implements which would "go to
eleven.*" With this device, you could calibrate everyone
to the Schmidt scale.

The Schmidt Sting Pain Index is amazing. With a
machine like this he could go on TV and have
arguments with someone else about which one is
most painful (and how does "Someone has fired a
staple into your cheek" not belong to a sting higher
on the scale?). With good marketing it is likely we
would all be trying this. Scary no...
